Strictly speaking, a periscope is an optical device that allows one to view and navigate the external environment.The acoustic periscope is a metaphor for mobile interaction that transparently exploit...
This paper is concerned with fast solution of high frequency acoustic scattering problems in two dimensions. We introduce a directional multiscale algorithm for the N-body problem of the two dimension...
This paper is concerned with the uncertainty quantification of high-frequency acoustic scattering from objects with random shape in two-dimensional space. Several new methods are introduced to efficie...
We introduce a novel finite-difference (FD) approach for seismic wave extrapolation in time.We derive the coefficients of the finite-difference operator from a lowrank approximation of the space-waven...
We present and analyze a multigrid algorithm for the acoustic single layer equation in two dimensions. The boundary element formulation of the equation is based on piecewise constant test functions an...
We study the magneto dynamic stability of acoustic streaming peristaltic flows of fluids induced by small amplitude surface acoustic wave propagation along the walls of a confined parallel plane micro...
Standard methods for describing the intensity distribution of mechanical and acoustic wave fields in the high frequency asymptotic limit are often based on flow transport equations.
A perturbation procedure for the modes and cut-off frequencies of cylindrical acoustic waveguides of arbitrary cross-section with a small temperature gradient along the walls was presented in [1, 2]. ...
